my sugar maple tree about 20 yrs old
What can I feed this tree? My driveway has been inundated with these acers. They are dried like a fall leaf. I am hoping there is nothing wrong with my tree. I have noticed the squirrels were breaking off green, healthy leaves this spring in large amounts.

It is hard to diagnose a tree without seeing it. As a general rule, you can give it some balanced fertilizer and treat it with a pesticide and fungicide (I like neem oil as it is both in one spray). This should fix many issues it may have. If the tree still shows decline after these treatments, you will want to have a arborist come and take a look at it so they can better diagnose the issue.
